How to add 2 models at once in Django Admin?
In Django v1.11.10 I have 2 models: Article and Files. In one article there can be many files attached. With scheme below I can create Article in admin panel, and then create File with <select> options to choose what Article it is related. But I want to create Article and at the same page add many File objects pressing "plus" button. Like dynamically. Is it possible? class Article(models.Model): title = models.CharField(max_length=100) description = models.TextField(blank=True) class File(models.Model): article = models.ForeignKey(Article, on_delete=models.CASCADE) name = models.CharField(max_length=100) path = models.FileField(upload_to=file_upload_folder) admin.py: from django.contrib import admin from .models import * admin.site.register(Article) admin.site.register(File) -

Inserting hyperlinks into pdf generated with pisa
Currently I am generating a pdf from a html template in django/python. Here is a relevant snipit from my view result = StringIO.StringIO() html = render_to_string(template='some_ref/pdf.html', { dictionary passed to template},) pdf = pisa.pisaDocument(StringIO.StringIO(html), dest=result) return HttpResponse(result.getvalue(), content_type='application/pdf') And my template is an html file that I would like to insert a hyperlink into. Something like <td style="padding-left: 5px;"> <a href="/something_here/?referral_type={{ template_variable }}">{{ referral_all.1 }}</a> </td> Actually, the pdf generates fine and the template variables are passed correctly and show in the pdf. What is inside the a tag is highlighted in blue as if you could click on it, but when I try to click on it, the link is not followed. I have seen pdfs before with clickable links, so I believe it can be done. Is there a way I can do this to make clickable hyperlinks on my pdf using pisa? -
Transfer users between Django servers
I have two types of Django servers. One is a central server that contains a master database. There's only one of these. Then there's an arbitrary number of client servers that contain their own databases. These client databases act as a cache for the master database. This is used for users. I a user tries to log in on client server 1, that server looks for the user in its database. If it's not there, it goes out to the central server and asks that server if the user exists in the master database. If so, the central server returns the users info so that the client server can store/cache it in its own database and then log the user in. Each successive time that user tries to log in, the user is found in the client database and it no longer has to go out to the central server. The central server returns the users information as JSON like so: { "username": "joe.bag.o.doughnuts", "id": 143, "password": "fksdfjfldskjf", } My issue here is the password. when I put the value in there as just user.password, it uses the encrypted version of that password. This is good because I don't want … -
How do I run migrations in Dockerized Django?
I followed a Docker + Django tutorial which was great, in that I could successfully build and run the website following the instructions. However, I can't for the life of me figure out how to successfully run a database migration after changing a model. Here are the steps I've taken: Clone the associated git repo Set up a virtual machine called dev with docker-machine create -d virtualbox dev and point to it with eval $(docker-machine env dev) Built and started it up with docker-compose build and docker-compose up -d Run initial migration with docker-compose run web python manage.py migrate. (This is the only time I'm able to run a migration that appears successful) Checked that the website works by navigating to the IP address returned by docker-machine ip dev Make a change to a model. I just added name = models.CharField(default='Unnamed', max_length=50, null=False) to the Item model in web/docker_django/apps/todo/models.py file. Update the image and restart the containers with docker-compose down --volumes, then docker-compose build, then docker-compose up --force-recreate -d Migration attempt number 1: docker-compose run web python manage.py makemigrations todo then docker-compose run web python manage.py migrate. After the makemigrations command it said Migrations for 'todo': 0001_initial.py: - Create model … -
Django Cart and Item Model - getting quantity to update
I am working on a Django cart application. I have two models Cart and Item. I am trying to get the quantity to update when an Item is added to the basket but cant get the views to work properly. I am having problems getting item_obj assignment to work - do I need to do anything with the model manager here? Any help is really appreciated.

Keras/TF trained model works as web app once, then value errors
TF community -- So I have trained a TensorFlow model using simple MNIST data. I'm using Keras' load_model in a Python script to pull it up and model.predict() to feed images to the model (once the data is properly transformed) so it can make predictions. This works well when running predict.py from the command line with various examples. But my goal is to web app-ify this prediction script so I can ping it from other apps. It was fairly easy to spin up a Django app and cause predict.py to run whenever a certain URL endpoint was hit. Given a random MNIST image sent in a POST request, the app will (usually correctly) make a prediction the first time, which I can see in the server logs in square brackets: 2018-02-09 17:49:40.639847: I C:\tf_jenkins\workspace\rel-win\M\windows-gpu\PY\35\tensorflow\core\common_runtime\gpu\gpu_device.cc:1195] Creating TensorFlow d evice (/device:GPU:0) -> (device: 0, name: GeForce GTX 1080 Ti, pci bus id: 0000:01:00.0, compute capability: 6.1) [5] [09/Feb/2018 17:49:43] "POST /predict/ HTTP/1.1" 200 1 Then, without fail, all subsequent posts generate errors until I restart the server with python manage.py runserver.

Highlight keyword in Django project
I have a django project which has a 'detail.html' file extended from 'base.html' file.This detail.html contains a search filter form.Here is my question in short "How to highlight the keyword specified in the search filter using jQuery" PS:I have already tried parsing the content of the detail.html and appending <span style="background-color: #FFFF00">Yellow text.</span> using javascript.

can't connect django 1.10 to mysql 5.7, mysqlclient installed but still get ImportError: No module named 'MySQLdb'
I created a virtual environment with python 3.5 then used pip to install mysqlclient. When I activate the venv and go into the python shell I can type import MySQLdb and then proceed to query my db without any trouble. However, in django 1.10.5 when I use this virtual environment I get ImportError: No module named 'MySQLdb' as soon as I start the local/dev server. For what it's worth, I also tried this process outside of a virtual environment but no success. I'm on windows and Pycharm and created the venv in CMD with administrator privileges.
